4 Claims.

The invention relates to new and useful improvements in pipes and the like for smokers use.

One object of the invention is to make novel provision whereby the. usual communicating opening between the bowl and stem of a pipe may be quickly and easily cleaned whenever necessary, simply by pushing forwardly upon the mouthpiece of the pipe.

A further object is to make novel provision whereby saliva cannot reach the bowl and whereby any accumulated saliva may be readily blown out, overcoming well known drawbacks heretofore encountered. f

l5 A still further object is to provide a construction which will be comparatively simpleI and inexpensive, yetefcient, desirable, and durable.

With the foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accompanying drawing.

. Fig. 1 is a longitudinal sectional view on line I-I of Fig. 2 showing the parts in smoking position.

Fig. 2 is a top plan view partly in horizontal section, with the parts positioned as in Fig. 1.

Fig. 3 is a View similar to Fig. 1 but showing the parts positioned to clean out the communieating opening between the bowl and stem.

Fig. 4 is a detail' sectional view, partly in elevation, showing the parts in saliva-blow-out position.

Fig. 5 is a fragmentary front perspective'view of one of the tubes.

i scope of the invention as claimed, variations may be made.

The numeral I0 denotes an outer metal tube for insertion into the usual stem II which is connected in the usual way with the pipe bowl I2.

At its rear end, the tube I0 is provided with a tubular enlargement I3 having a front wall I4 to abut the rear end of the stem II, the front end of said tube I0 and the rear end of said enlargement I3 being both open.

A smoke-conducting and saliva-collecting tube I5 passes slidably and rotatably through the tube IIJ, the rear end of said tube I5 having appropriate provision, such as screw threads I6 for connesting it with the front end of a mouth-piece I'I.

,55 The tube I5 is provided with a wall I8 abutting (Cl. ISI- 215) the front end of this mouth-piece and closing the rear end of the tubular enlargement I3 of the outer tube I0. Between this wall I8 and the wall I 4 of the enlargement I3,-a coiled compression spring I9 surrounds the tube I5 to normally hold this tube in a normal rearward position. When the mouth-piece Il is pushed forwardly, however, the spring I9 compresses and the tube I5 slides forwardly. This provision is made for two reasons. Iteffects cleaning-out of the usual 10 communicating opening 2|] between the bowl I2 and the stem II, in a manner hereinafter explained, and it unlocks tube I5 from a normal fixed relation with tube I0, permitting rotation of said tube I5 to a saliva-blow-out position, as 15 also explained hereinafter.

In the present disclosure, the front end of the tube I5 is reduced as shown at I5a and is provided with a forwardly projecting pin 2I which normally occupies ak position behind the 20 opening 20. However, when the tube I5 is slid forwardly by pushing upon the mouth-piece I'I, this pin 2| enters the opening 20 to effectively clean-out said opening and permit free passage of smoke therethrough, the cleaning operation 25 being quickly and easily performed whenever necessary.

I have illustrated a transverse smoke passage 22 in the reduced tube end I5a, and a longitudinal smoke passage 23 leading from said pas- 30 sage 22 into the main interior portion of the tube I5, said passage 23 being preferably in the form of a small tube projecting rearwardly to some extent into said main interior portion of said tube I5. Slidable in the passage or tube 23 is a 35 j forwardly closing check valve 24,. the opening movement of which is limited by a pin or the like 25. While the valve 24 freely opens rearwardly to admit smoke into'the tube'l5, it closes forwardly to prevent any saliva reaching the pipe 40 bowl. This saliva may be discharged from time to time as will now be explained.

The lower side of the outer tube I0 is formed with a saliva-blow-out opening 25 and the upper side of the tube I5 is providedl with a similar 45 opening 21 for registration with said opening 25 when said tube I5 is slid forwardly to a predetermined extent and rotated to a predetermined extent. This is, of course, done when the tube Il) is withdrawn from the .pipe stem II and any ac- 50 cumulated saliva may then be easily blown out of said tube I5. The parts are then restored to normal and the tube ID again inserted into the stem For normally locking the tubes I0 and I5 55 against relative rotation and for limiting the relative rotation of said tubes to saliva-blow-out position and back to normal when the locking means is released, I make nov-el provision, preferably of the construction now to be described. A pin or stud 28 is rigidly secured in any suitable Way, for example by soldering, to the front portion of the tube I5 and projects laterally therefrom, the front portion of the outer tube I being provided with a longitudinal slot 29 in the rear end of which said pin or stud 28 is normally held due to the action of the spring I9 forcing said tube I5 rearwardly (see Fig. 4). When the tube I5 is slid forwardly, however, by forwardly pushing the mouth-piece I1, the pin or stud 28 slides tothe front end of the slot 29 and is then receivable in an arcuate slot 3l] extending substantially throughout half the circumference of the tube I. Forward sliding of the tube I brings its saliva-blow-out port 2l in the same transverse plane with the port 25 of the tube I8, and rotation of said tube I5 with the stud or pin 28 moving in the slot 38, then brings said port 2 into alinement with said port 25. Rotation of the tube I5 to its saliva-bloW-out position is limited by striking of the pin or stud 28 against one end wall of the slot 30, and rotation of said tube I5 in backto-normal direction, is limited by striking of said pin or stud against the other end wall of said slot. In the present disclosure, both the slot 29 and slot 3d open through the forward extremity of the tube III, although this is of course not essential. One of the portions to which I have referred as an end wall of the slot 38, is shown at SI and the other at SIP', and while 3l might be considered a portion of one side wall of the slot 29, it seems preferable for purposes of description to consider it as an end Wall of slot 38.

It will be seen from the foregoing that novel and advantageous provision has been made for carrying out the objects of the invention. Whenever it is necessary to clean out opening 28, this may be quickly and easily done simply by pushing forwardly upon the mouth-piece Il', causing forward movement of the tube I5 and similar movement of the clean-out pin 2l. When accumulated saliva is to be discharged, the tube Ill and parts carried thereby are withdrawn from the pipe stem II, the mouth-piece I'i is pushed forwardly until the pin or stud 28 will clear the slot. 29, andv rotation of said mouth-piece I'I in the proper direction, will then serve to rotate the tube I5 to bring its saliva-blow-out port 2l in alinement with the corresponding port 28 of the tube I il. Blowing-into the mouth-piece II then causes. discharges of saliva through the two openings 2l and` 2S, the check valve 24 being of course held closed by the air pressure. The rotation of the tube I5 to its saliva-blow-out position and back to normal is limited by the slot ends Sla and 3i respectively, andV as soon as the pin or stud 28 strikes said end 3I, the spring I8 slides the tube I5 rearwardly, again positioning said pin or stud inthe rear end of the slot 29 and thus locking the two tubes I5 and-Ill against any relative rotation until relatively slid to the required extent.

As excellent results may be obtained from the details shown and described, .they are preferably followed. However, attention is again invited to the possibility of making variations within the scope of the invention as. claimed. Moreover, while the invention isV disclosed in connection with a pipe, it could well be used with a cigar or cigarette holder, simply by inserting the tube I0 into the stem of the holder and providing a suitable mouthpiece on the rear end of the tube I5. The pin 2| could be used to form a draught opening in the rear end of a cigar if the invention be used with a cigar holder, and forward sliding of the tube I5 could be utilized to cause ejection of the cigar butt after smoking. Cigarette butts could, of course, be ejected in the same manner from a cigarette holder associated with the invention.
